某电站坝基破碎带密集区综合变形模量研究

拱坝作为水电站常用坝型,对坝基岩体要求非常高,破碎带常在坝基岩体中分布较多,存在一定的厚度,且不可能完全挖除。本文通过对影响坝基开挖后岩体质量的破碎带密集区综合变形模量的研究,结合大量的声波和现场实测数据,对坝基开挖后的岩体质量进行定量的评价,也可作为坝基开挖后处理局部较差岩体的依据。

STUDY ON COMPREHENSIVE DEFORMATION MODULUS ON CONTACT FACE FAULT ZONES COMPRESSION AREA OF HYDROPOWER PROJECT

Arch Dam frequently use of the Hydropower Project, and it is strictly requests to the rockmasses quality. The fault zones extensive distribute contact face rockmasses,have its thickness and is impossible to dig out completely. Based on the study of comprehensive deformation modulus on contact face rockmasses quality fault zones compression area of Hydropower Project,associative the massive sound waves data and on-site actual measured data, we can take a quantitative evaluation to the excavated rockmasses quality of contact face,and this study can be a evidence to treating local bad rockmasses of excavated contact face,and will do some help for other similar project.
